the same.

This invention relates to gages for machines involving mechanism for operating upon sheets or webs of paper, or other material, and has for its object to provide a novel form of sheet gage with electrical actuating means which may be operated to adjust the gage either from a point adjacent thereto, or from a remote point. It is common to employ gages of this character in printing presses and also in other machines where sheets or webs are fed, and the invention is applicable to gages of this character generally.

In the drawings Figure l is a side elevation of the gage;

Fig. 2 is a plan view of the same;

Fig. 8 is a transverse section on line 11--11 of Fig. 5;

Fig. 4 is a similar section on line 12-l2 of Fig. 5; I

Fig. 5 is a longitudinal sectional view of the left-hand portion of the device, as shown in Fig. 2;

Fig. 6 is a bottom plan view of the armature and actuating pawls; and

Fig. 7 is a fragmental plan view of the guide-plate showing the relation of the fingers thereof to the gage-plate.

Referring to the drawings, the gage comprises a tubular housing 1, secured to the forward end of a box-like casing 1 which latter has a slidably adjustable connection on the top surface of a bracket 1". The adj ustment of this bracket is efiected by means of a thumb-screw 1 engaging lugs on the members 1 and 1 respectively. The bracket member 1 is provided with a clamp collar P, by means of which the gage is adjustably mounted on the rock shaft of the printing press when the gage is used in connection with a press, as will be understood. In order to securely lock the movable member of the gage to the bracket 1*, there is provided a vertical clamping screw 1 which passes through a slot l in a lateral flange of the casing 1 and engages the bracket 1 Mountedfor rotary movement within the tube 1 is a spindle 12 which carries at its forward end, a disk 16 which constitutes the i.

gage plate and is associated with adjustable spring guard members 17. The rear end of the spindle 12 is in screw-threaded engagement with a boss or projection on the casing l, as shown in Fig. 5, so that when said spindle 12 is rotated, it will be moved in and out longitudinally with respect to the tube 1 and will effect a corresponding movement of the gage plate 16, which latter, because of its circular contour, revolves between the fingers 12 of the feed plate 12', over which the sheets or webs, which are indicated in Fig. 1 of the drawing at 16, are fed. The feed plate 12", as disclosed in Fig. 7, is provided with spaced fingers 12', so that the gage plate 16 may extend below the surface of the feed plate and will not contact therewith. The advantage of this arrangement may be readily seen, inasmuch as it will insure the contacting of the web or sheet with a considerable portion of the face of the gage plate 16.

In order to effect the rotary movement of the spindle 12, in either direction, the latter is provided with two oppositely disposed ratchets 20 and 21, which ratchets are oppositely rotated by means of pawls 29 and 29 respectively. These pawls are pivoted to the lower face of a swinging armature 27, said pawls belng normally held in engagement with their cooperating ratchets by means of "springs 31 and 31 as clearly shown in Figs. 4 and 6, which springs are adapted to retain the pawl in their suspended positions, such as disclosed in Fig. 4, so that upon the rotation of the spindle by one of the pawls, and the subsequent movement of the armature 27 to its neutral position under the action of the springs 40, the other pawl will move on to the next succeeding tooth. The armature 27 is pivoted on a pintle 27 in the upper part of the casing 1 and is disposed between two pairs of electro-magnets 25 and 26, which are secured to the sides of the casing 1 so that when the respective pairs of magnets are energized, the armature will be swung in one direction or the other, and thereby rotate the spindle 12 a step at a time to either advance or retract the spindle. In order to maintain the armature normally in its central position, the said armature is provided with "a T-shaped head portion,the opposite sides of which are engaged by flat springs to-a0, which springs, inturn, are secured ;.to a cross piece 35 attached within the casing l Inorder to lock the spindle 12 in any of "its adjusted positions, there is provided an electro-magnet '35 which consists of two spools attached to the under face of the cross piece 35", which electro-magnet 35 coopera crossre'd 36 within the casing and is nor- 15'mally; retracted i-rom the magnet 35 by a e ates with an armature 36which is pivoted on springfl3l3f", as shown in Fig. 3, to torcea locking pawl or detent 37iinto cngagement with a ratchet-22 which is secured to the spindle rlfi, The circuits to the respective magnets 25,26=and are similar to the circuits illustratedin Fig. 9 of the drawings in my Patent, No. 1,189,264, dated July 4;, 1916, for paper feedgages, and said circuits are controlled or operated in the same manner, namely, by suitable push buttons arranged at some convenient point of control mediately at the gage by operating the proper push button p or p or byoperat ing one of the corresponding remote push buttons.- If, for example, the operator ob- 7 serves that one of the gages should be advanced slightly, he pushes the appropriate remote button, for instance, and thereby energizesth'e magnets 25 or 26 and also the magnet 35, whichlatter unlocks'the spindle l2landthe former of which rotate the same i one step. If this extent of adjustment is not 'sufiicient, the actuation of the push button is repeated untilthe desired adjustment is obtained, which adjustment, it will be nnderstood, proceeds step by step. Instead of effecting-the adjustment from the point of distant control, the voperator may adjust the i gage by means "of either of the push buttons 29" or 29 located onthe casing 1 It is obvious that the'invention maybe applied to any of the well-known types o'f gages, or may besu'bstitutedfor the various gages now employed in machines involving the feeding of sheets or webs of materials,
